I looked into being homeschooled awhile ago because I was curious about it, not because I seriously thought about doing it. If you do a search for it on the net, there is lots of info out there. I found a couple schools designed for high school homeschoolers where they send you the lessons and work, you complete it and mail it back, like by correspondence, because lots of kids that are homeschooled, especially in high school, do not have private tutors or parents who know everything about each specific subject.
Homeschooling sounds like fun in that you can move at your own pace, and study things that might not be offered at your school. Plus you can study at home, and there is something about being at home which is just nice IMO. But on the other hand, I realized that I would miss my friends at school, as well as miss out on all the other high school activities - football games, homecoming, winter formal, assemblies, as well as just spending time at school with friends. It just wouldn't be the same IMO.
